Exhaust

[Jeremy'sSVX]

Basically I'm looking to do a new cat/back exhaust this summer. I'm going to buy a resonator and a muffler and do everything else myself with 2.5" tubing.

I want it to sound basically like this, I know its a corolla, hahaha but that sounds beautiful to me

I'm thinking this resonator:

I've been looking around at mufflers and I'm not sure what i should get. I've been looking at a few options and i wanna see if anyone has any opinions on anything.

1. The bullet muffler that Tom uses on his AWD bolt on kit. ($99)

2. The magnaflow Muffler from dale. ($105)

3. Borla Turbo XL($242)

4. Borla Pro XS ($169)

I want a clean sound, similar to that of a European car. Maybe the sound of an Audi. I don't want anything throaty sounding thats why I'm leaning away from the magnaflow. I also want it a little louder than the stock system but not obnoxiously loud.

Does any one have any suggestions for me about any of these or any other components to help me obtain what i want from my fine svx. I would love a stebro but theres no way i can afford one of those.

Thanks for any help.

When I did mine I made it more straight line and free flowing with 2 1/2 in pipes, deleted the stock resonator and went through a flowmaster camero style free flowing performance muffler(not sure of the model) into 3 1/2 in tips and I've been told it sounds like a formula 1 racer or a Ferrari. It's quite throaty but also very clean crisp, and very nice sounding...

I'm going to do some audio clips this summer along with many other things. if you're still trying to decide by then maybe mine will help you too.

If you search on the forum there are quite a few links to videos and also some audio clips posted. look around see what you like. Good luck!

[Jeremy'sSVX]

Hmm i would love to hear your clips. Would you mind watching that video i posted and compare it to that? hahah
Thanks a lot

Anyone? Ideas?

Exhaust is the kind of thing where it really does just come down to your personal opinion. You could ask ten different people on here what they like, and you'd probably get ten different answers. Obviously we don't have as many options as most folks do in this regard, but asking someone what sounds "the best" is a surefire way to get nowhere fast.

For what it's worth, I love the sound of my 2.5" catback with a magnaflow muffler. Its barely louder than stock but has a throaty, racey tone to it. I wouldn't have it any other way.

Another thing about exhaust systems is the fact that they will sound different depending on your engine mods. Cam change? Exhaust note and volume may change. Compression change? Same thing.

[Johnybeas]

that's what I'm not looking forward to. lol I want the more power and wanna turbo... but I love the way it sounds right now! I can do clips next month. I'll listen to the clips though

I have an old clip from my magnaflow exhaust.

www.timeng.net/downloads/exhaust.avi

The knocking sound is the lens cap knocking against the microphone.

I now have the bullet muffler, which sounds similar but deeper, smoother, and a little quieter.

[Nevin]

Here's a video from the other week of my exhaust. Had a bit of an exhaust leak at the time, but you can't really tell a difference, since this is an in-car video anyway.

2.5" mandrel bends with a gutted main cat, and magnaflow muffler.

[YourConfused]

Here is a clip that didn't really upload correctly, but has sound none the less.

http://www.youtube.com/watch?v=I2npCO_twkg

The first of the 3 audio parts is my camera buzzing on the steering column at highway speeds and the other 2 are from a a stop sign, turning and then accelerating to about 70mph. You can hear the turn signal tick tick since it is my camera sitting on the pass seat w/ in car noise from the windows being down.

[RoughSilver92]

Sounds good Nevin.
And that video is a hoot.:lol:

[Jeremy'sSVX]

Okay so I'm getting ready to do my exhaust (as listed below in OP) in the very near future.

I decided to go with the Magnaflow resonator and the borla pro xs transverse muffler and I'm going to have my own 2.5" tubing made.

I was also looking on dayles site and saw that he had hiflow cats. And i was just curious if you guys think it would be worth my while to do the cat while i'm down there? Would it make much of a difference to do it or should i save my money for something else?

This is the cat that I'm talking about:

You can get them cheaper on ebay.

You can get them cheaper on ebay.

hahahah...:lol:

Anyone? Ideas?
If a magnaflow is too loud for you go with stebro...its got throat..but quiter than magnaflow...I have both (on different cars of course)

Yeah i was gonna look else where (shh don't tell dayle :cool:) But i was mainly asking if you guys think it would be worth it to replace the cat. Would it give me better performance or sound?

Also i noticed on ebay it says its 2.5" in and 2.0" but the resonator and muffler are 2.5" in and 2.5" out. Would that be a problem or would that be an easy fix?

[redlightningsvx]

For about a stock engine, Most people I see use a 2.5in from the manifolds to cat and 2in back from the cat to muffler. But if the muffler and resonator you have are 2.5in the i would just get a coupler on the cat.

[Jeremy'sSVX]

So would replacing the cats definitely be worth it?

[redlightningsvx]

I would will your down there.

2" dual from the manifolds to the main cat

2.5" single from the main cat to resonator and transverse muffler

[redlightningsvx]

oppss I got them backwards. Thanks for correcting me Tom.

[Jeremy'sSVX]

Awesome that'll work perfect then I definitely will do that then, thanks a lot guys!

[Jeremy'sSVX]

Okay so i have one more final question if i did all that i said (muffler, resonator, cats and 2.5" pipe) how loud do you guys think it would be? Outside of cosmetic stuff my engine is completely stock.

Anyone who has done an entire exhaust system similar to mine?

Thanks.

[SVXRide]

It will not be much louder than stock.

Confused by this! I know nothing about flow dynamics and such but just using my 'common sense', I would make an exhaust that would be the same size all the way through OR start off with a max flow/least restriction diameter and step it down as it gets closer to the muffler. Make it smaller by .25 perhaps but no more. My reasoning for this is to maximize flow but keep restriction at a minimal.

Why would you go larger the further you move out from the exhaust ports? Wouldn't that slow down the exhaust flow?


RE-EDIT!!!! Nevermind.....you are going from a dual to a single. I'm thinking straight dual all the way though...
